Description

BACKGROUND THE INVENTION

A Marking or labeling of CDs / DVDs (Compact Discs / Digital Video disks (compact disks / digital video disks)) was in the Past routinely accomplished by screen printing. Although this method a size Diversity regarding of tag content, it is for run lengths of less than 300-400 Discs or disks tend not to be cost effective as the fixed costs specific materials and constructions of all plates in each Run worn together or used. When screen printing a template of the image is created, with the CD / DVD in contact brought, and then is inked using a squeegee the template surface distributed. There, where openings in the template, the ink reaches the surface of the CD / DVD, which creates the image. The creation of the template is a complicated, time consuming and expensive process.

In recent Years ago a significant increase in the use of CD / DVD disks as Data distribution support means to an increased Requirement to provide custom marking content to reflect the data content of the CD / DVD. For these applications provides The screen printing of markings is a dilemma as plates go there designed to be able to that custom user information is standardized CD / DVD formats are recorded.

A CD / DVD is a data storage medium with high volume and long life. One of the most basic types of CD / DVDs is a compact disc read only memory CD / DVD (CD-ROM CD / DVD). It contains an injection molded polycarbonate plastic substrate containing a spiral track of variable spaced pits, called dimples, which pass through a non-recessed groove Surface, which is referred to as a web, are separated. Information is recovered by focusing a low powered infrared laser beam onto the spiral track of dimples and lands in the substrate of the disk. The height difference between the dimples and the adjacent lands produces a phase shift that causes destructive interference in the reflected beam. The effect of these differences in the reflected beam modulates the intensity of light reflected back to a photodiode detector from 30% (pits) up to 70% (ridges). This modulated high frequency signal is then manipulated, used for tracking, focusing and velocity control, and then decoded and translated into useful data.

Under a CD-recordable CD / DVD (CD-R-CD / DVD) is understood as a CD / DVD, the usual can be described by a laser beam, as opposed to a CD-ROM, at the information is reproduced by injection molding. cyanine, Phthalocyanine and metallized azo dyes are commonly used dyes, coated in a polymer binder in the dye layer are. The metallized reflective layer is usually CD-R made of gold and usually on CD-ROM Aluminum. For a CD / DVD writer to write to a CD-R CD / DVD A laser beam illuminates the dye polymers through the polycarbonate substrate through, while the plate turns.

in the Unlike a conventional one CD / ROM CD / DVD contains the substrate of a CD-R-CD / DVD no trace of dimples and webs. Instead contains the substrate has a slightly eccentric spiral pregroove. If the plate at the right speed under the focused Laser beam is generated by the Vorrille generated by the photodetector reflected reflected light a photocurrent that was critical tracking, Motor control and focus signal provides, so that the recorder on track remains. The most important difference between a CD-R-CD / DVD and a CD-ROM CD / DVD is the integration of a sensitive dye layer into the CD-R to record the data to be recorded.

dates are written into the CD-R when the heat from the laser causes that the dye layer chemically changes at these points, whereby readable labels in the dye polymer be formatted. The impaired Dye polymers in the labeled regions are less reflective as the unmarked regions. During the reading process is scanning a low power laser is the dye polymer layer in a recorded CD-R-CD / DVD. The laser light is directly from however, the marked area is reflected in the unmarked regions Regions scattered or diminished. The written in the dye Marks mimic the light scattering effects of shaped CD-ROM pits, being the intensity modulate the reflected back to the photodiode detector light beam and reflection abilities Deliver close enough (28% and 70%) at a conventional rate CD-ROM lie to pass through a device that reads a CD-ROM designed to be read.

in the Unlike CD-R allows a CD overwritable CD / DVD (CD-RW CD / DVD) that data is often written to a CD / DVD become. To do this, a CD-RW CD / DVD uses a Six-layer design made from a polycarbonate substrate, a lower dielectric layer and phase change alloy recording layer, an upper dielectric layer, an aluminum alloy reflector and a protective lacquer topcoat.

As CD-R disks also use a CD-RW-CD / DVD a polycarbonate substrate, in the one spiral Vorrille is shaped. The real heart of CD-RW CD / DVD technology, the a reusability possible makes is the recording layer. The system made of a quaternary phase change alloy composed of silver, indium, antimony and tellurium is, works on the principle of changing the phase of the recording material between a higher one reflective crystalline state and a lower reflective amorphous state. Unlike other available on the market Phase change storage implementations, the "bright burn "or data Write by adding areas of increased reflectivity Creating a light-scattering background is a CD-RW a "dark burn "system, the marks of a lower reflectivity on a reflective surface writes. This ensures that the resulting trace of amorphous marks and crystalline interspaces visually the pattern of dimples and webs on a shaped CD-ROM CD / DVD visually comes as close as possible.

When applied, the phase change material is amorphous, but a CD-RW disc is "preinitialized" to a crystalline state by default.CD-RW is a direct overwrite system (DOW system, DOW = Direct Overwrite), which means that existing information be overwritten with new data without erasing what already exists. To describe the CD-RW disc (producing a lower reflectivity mark), a powerful 780nm (8-14mW) laser beam is focused into the pregroove, and the laser energy is absorbed and heats the phase change alloy to it Melting point (600 degrees Celsius). As it cools, it glases back to the amorphous state to produce the phase change. To erase the CD-RW disc (to produce a higher reflectivity mark), a lower power laser (4-8 mg) is focused on the pregroove and heats the alloy to its glass transition temperature (200 degrees Celsius) ). As it cools, it forms a crystalline state.

1 is a comparative illustration of the layers of a CD-ROM, CD-R or CD-RW CD / DVD. As can be seen, all three have a substrate layer on the read / write surface, a protective layer on the opposite surface, and a reflective layer between the two surface layers. The CD-R and CD-RW CD / DVDs both have a recording layer between the substrate layer and the reflective layer: wherein the dye layer in the CD-R-CD / DVD is the recording layer, and the metal phase change layer (metal PC- Layer, PC = phase change) consisting of a quaternary phase change metal alloy with silver, indium, antimony and tellurium, in which CD-RW-CD / DVD is the recording layer. In addition, the CD-RW CD / DVD includes a dielectric film layer on both sides of the metal PC layer.

The This invention relates generally to a method of infrared laser "marking" a CD-R-CD / DVD in an otherwise standard CD-R recorder. At a embodiment The data laser also functions as a marker laser, and the same Servo can use the laser for both move the data as well as the marker function. With another embodiment need the recording device a low power laser marking above the disk (on the non-data side) Tracks tracked, as well as the necessary Drive electronics for the marking laser. In this embodiment, the marking laser be moved by the same servo that moves the data laser, or the marker laser and the data laser can be separated by two separate servos to be moved. At the time of a data recording, the marker pattern, that on the basis of a commercial one Marker generation software is created, rasterized (or spiraled) and fed into the marking laser. In areas, in which the marker laser illuminates the plate, the laser-sensitive coating their color, creating a marking pattern is left on top of the CD-R-CD / DVD.
